Adam Dabrowski is said to have threatened to leak intimate photos of a woman if she didn’t perform sexual acts or pay him. Dabrowski has been charged with extortion, sexual assault, and the nonconsensual distribution of intimate images, among other charges. Police also said they seized cocaine, crack cocaine, marijuana, and pepper spray during Dabrowski’s arrest.

The woman, whose name has not been released by police, filed a complaint to the London Police Service (LPS) on Saturday stating that she met Dabrowski on Tinder and that he began threatening her on 14th February, according to a press release from the LPS.

The LPS Sexual Assault and Child Abuse Section found that the perpetrator also regularly visited London, Waterloo, Edmonton, and Calgary, leading investigators to believe that there are other victims. However, an LPS spokesperson told Gizmodo in an email, “We have not had any other victims come forward to date.”

Dabrowski is in custody and supposed to return to court today. The LPS is asking that people should reach out to them or their local police if they think they have also been victimised by him.

This is certainly not the first time someone has used social networks as a vehicle to sexually exploit women online. Leigh Abbot, a 37-year-old man in Australia, made nearly $160,000 AUD (£89,950) by threatening to release intimate photos of women he forged relationships with on Tinder and Plenty of Fish. And there are a number of websites and forums dedicated to sharing users’ sexually explicit photos from Snapchat—photos screengrabbed and likely leaked online without their permission.

What’s promising about this case is the urgency with which the police department launched an investigation and ultimately charged the perpetrator. As we’ve seen before, acting without expedition can seriously cost a revenge porn victim.
